C2 - Basic Unofficial ROM

bencebacsi

This is an unofficial SP Flash Tool release of the

V1.6_20171019 Basic Edition (UMI OS 2.0)

system software for

UMIDIGI C2

Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!

WARNING!

If you have this version installed on your phone, your warranty might be voided according to your seller's policy! In case of a warranty return, we recommend you to flash an official stock ROM.

If you have this version installed on your phone, OTA updates cannot be installed. Basic Edition version OTA updates will not be provided. You can any time return to an official stuck ROM (flashing only the system partition of the same version is enough) to be able to receive factory OTA updates again.

If you flash the Basic Edition version for the first time, it is highly recommended to flash it in Firmware Upgrade mode (your user data will be erased) in order to remove the updates and saved data of the removed apps as well. Later updates can be flashed without the userdata partition.

Changelog:

• Replacable default launcher (once you set it as default, you must uninstall your custom launcher to be able to use the system launcher again)
• Initiator launcher replaced by Google Pixel launcher as the system launcher
• Not system-sensitive custom apps have been removed
  

         List of removed apps: 360 Security, FreeShare, QuickTouch, TouchPal 2017, App Store, Intelligent Aggregating Page, Power Master, 9Apps, News Republic, UC Browser, Avatar Master, Anti-theft, App Cleanup, Initiator (system launcher), Property System, 360 Clone

ROM: >>>>> UMIDIGI_C2_7.0.042.P1.1710192157.C2.VZ_YM_C2_OE_Basic.rar <<<<< No DB files included

Extract the .rar file before use. The scatter file (MT6750_Android_scatter.txt) is inside the extracted folder, together with the other components

SPFT: SP_Flash_Tool_v5.1752.rar

VCOM driver: Windows 10 can automatically install it. Please make sure that your Windows is logged in with administrator rights and your computer has a working internet connection when first time connecting your phone.

Here's an optional solution to start the flashing process on your UMIDIGI C2 if the standard method doesn't work.

It's especially useful if your phone is bricked or is stuck in bootloop

1. Connect your UMIDIGI C2 to USB.

2. Start the flashing process with the Download button in the flasher app.

3. Press and keep pressed the power button of your phone until the flashing process starts (red bar appears at the bottom of the app window), then release it. In this process you have to keep the power button pressed for about 10 seconds.

4. Wait until the flashing process finishes.

Hi,
This build is based on the latest official ROM but as a result, it's not an official software  ...

Hi,

WARNING!
Until you have this version installed on your phone, your warranty is voided! YOU ARE WARNED!

I don't understand why you said this, is just a ROM!

Thank you for the job!

Hi,

Hi,
This build is based on the latest official ROM but as a result, it's not an official software release, so in case of a warranty return, your seller is not obligated to accept your defective device if it contains a modified, unofficial software. Practically, you may use this Basic Edition build with confidence but in case of a warranty return, first you have to flash an official ROM build, which is able to receive and install OTA updates. The Basic Edition will receive only flash tool updates.

Hi,

How can I change launcher? Pixel is quite good but Evie is a waaay better. The is no Home option in Applications as usually in Android 7 :-( Evie can't do it itself only reminds to switch default launcher option.
BTW Great job! Thank you so much. Now my C2 's software stack is finally acceptable.

Bencebacsi, thank you for great hint and support. I couldn't find this option starting Evie, but I hit the idea that I could have set up (by accident) Pixel as default launcher. And it was the case as I suppose. I flashed phone again, installed Evie, launched it and got the msg which you captured on the screenshot. So my problem was solved.
Thanky you! :-)
